Cymbidiums come from anything from 2500m in the Himalayas, where they get a snow cap every Winter, to the depths of the wettest jungles you can imagine. Consequently, there is no uniform rule for them. However, virtually all of the large flowered species and their progeny are monsoonal, which means that they need a dry rest in Winter. This is usually accompanied by very bright sun in the wild, and with temperatures which may be low or high, depending on their habitat. As a rule, they will not flower unless given such a rest - typically, in the Northern hemisphere, receiving no water whatsoever between October and March. Many, such as C. sinense, iridioides and traceanum flower whilst dry, as they do in the wild. If they are kept warm and wet, they will grow prolifically, but seldom flower. ______________________________ Oliver Sparrow +44 (0)20 7736 9716 www.chforum.org _______________________________________________ the OrchidGuide Digest (OGD) orchids@orchidguide.com http://orchidguide.com/mailman/listinfo/orchids_orchidguide.com
